甘肃省肃北县跃进山南铜钨多金属矿地质特征分析

跃进山南铜钨多金属矿属最新发现矿点,大地构造背景属塔里木板块与哈萨克斯坦板块的交汇部位南侧,成矿区带属马庄山—狼娃山—黑鹰山铁、金、铜、铅、锌、钨和锡成矿带。矿体赋存于下石炭统白山组二岩段矽卡岩中,区内岩浆活动、构造作用、变质作用均较发育,主要成矿类型属矽卡岩型矿床。该区内铜钨多金属成矿与地层、构造、岩浆活动关系密切,并指明了找矿标志,该矿床的发现对北山北带探寻矽卡岩型钨矿床具重要意义。

Geological characteristics of copper-tungsten polymetallic deposit in the south of Yuejinshan, Subei county, Gansu Province

The copper-tungsten polymetallic deposit is a newly discovered deposit in the south of Yuejinshan. From the geotectonic background, it is located in the south of Tarim Plate and Kazakhstan plate intersection zone,it belongs to the metallogenic belt of iron, gold, copper, lead, zinc, tungsten and tin in mazhuang mountain-langwa mountain-heiying mountain.Theorebodies occur in skarn of the 2nd member of Baishan formation of the lower carboniferous. Magmatism, tectonism and metamorphism are well developed in the area. The main metallogenic type is skarn deposit. The metallogeny of copper-tungsten polymetallic deposit in this area is closely related to strata, structure and magmatic activity,and the prospecting criteria are pointed out. The discovery of this deposit is of great significance to the exploration of skarn type tungsten deposit in Beishan north belt.
